Introduction：There is no correlation between the English expressions with rich connotations between the Anglo-American culture and the Eastern culture，which makes it difficult to find the corresponding to express Chinese idiom at the time of translation. In this case，it has caused some obstacles for cross-cultural translation. Most of the translations only retain their own meaning，and discard some of the image meaning and cultural connotation of English，or use other Chinese metaphors in English so that metaphor can be replaced.

1 The cultural differences between English and Chinese idiom

Chinese and English are the ancient languages used by people in the long years. Under different development backgrounds and different use environments，the two languages gradually evolved into different characteristics，and let us see two in the study of language. The differences in culture and the reasons for these differences.

There are obvious differences in geographical location between the UK and China. The composition and application of many vocabularies are due to the specialization of the geographical environment.

1.2 Differences of customs in english-chinese translation

Custom is a social phenomenon. Bread，for example，in Britain，bread is the main food. The idiom "earn bread" is now translated to earn a living. Or taking bread out of someone's mouth，translated as taking someone's bowl. But in China，because jiaozi is a very important food，So the custom is different，the idiom that each place produces is different also.

1.3 Differences in history

Both China and the UK have a long history and rich culture，many idioms are mythological mapping idiom with very obvious mythological features. the UK pays attention to Greek culture，while China pays more attention to some mythological stories.

Some English idioms and Chinese idioms have the same meaning，the same emotional color，the same or similar image，their own national color is not very strong，in this case，translation can borrow its target language. 例如：Look foraneedlein ahaystack 大海撈針。

2.4 Annotation

Many English idioms are derived from historical allusions. They cannot be directly understood and translated from the literal language. At this time，literal translation and annotation should be adopted. For example，"as fair as Helen" is translated as "如海倫般美麗".
